"hi kids how's your practice going welcome to lido q a video i am vinit your lido tutor bringing you this question on your screen a freely falling object travels 4.9 meter in the first second 14.1 meter in the second second 24.5 meter in the third second and so on this data shows the motion of a freely falling object in a case of now clearly the distance traveled per unit of time is increasing so it cannot be a uniform motion neither can it be a uniform velocity now the speed is increasing constantly with every second therefore there is acceleration so the answer is uniform acceleration right guys isn't that easy right if you still have a doubt though please leave a comment below do like the video and subscribe to our channel i'll see you in our next video until then bye guys keep learning keep flourish "
